Scientists have invented a major new advance in DNA nanotechnology. Dubbed 'single-stranded origami,' their new strategy uses one long, thin noodle-like strand of DNA, or its chemical cousin RNA ...

Short circular DNA nanotechnology. Comparatively, short circular DNA nanotechnology is created following a series of circularization steps that convert the short linear template strand into a ...

Sometimes the lagging strand synthesis stops, but the leading strand continues to grow. This shows up as a dark area in the glowing strand, because the dye doesn't stick to single-stranded DNA.

Remote-controlled microflow using light-controlled state transitions within DNA condensates has been reported by scientists ...

For the first time, researchers at the University of California, Davis, have watched single strands of DNA being prepped for repair. The research, published this week in the journal Nature, has ...

Sometimes the lagging strand synthesis stops, but the leading strand continues to grow. This shows up as a dark area in the glowing strand, because the dye doesn’t stick to single-stranded DNA. “We’ve ...

RecA is a bacterial protein that is crucial for repairing double-stranded breaks in DNA via the process of homologous recombination. RecA binds to single-stranded DNA, searches along a separate piece ...

He and his colleagues used a sperm DNA assay (SpermComet, Examen) to assess sperm quality and the effects of single- and double-stranded DNA breaks on ICSI outcomes.They compared sperm from the ...
